The changes in volume after LA and at each follow-up.

	Nodule numbers (n)	Maximum diameter (cm)	Volume (mL)	Volume reduction ratio (%)
Before ablation	118	1.36–4.72 ()	0.72–34.9 ()	—
One day later	118	1.76–4.92 ()	1.78–38.4 ()	—
One month later	104	1.48–3.95 ()	0.05–20.6 ()	42.3
Three months later	96	1.21–3.72 ()	0.74–17.5 ()	53.5
Six months later	75	1.06–3.12 ()	0.41–8.41 ()	77.1
Twelve months later	52	0.00–1.28 ()	()	96.5
Eighteen months later	48	0.00–0.78 ()	0.00–0.12 ()	98.8
